                                                                              10月23日,經過57小時的連續澆筑,由中鐵四局G36寧洛高速公路明光至蚌埠段改擴建工程TJ-03標項目承建的淮河特大橋主墩承臺順利澆筑完成,標志著大橋主墩工程施工進入可視化階段,為下一步主墩出水提供了先決條件。

                                                                              寧洛高速公路明光至蚌埠段改擴建工程項目起于明光市明光東互通,終于梅橋鎮,路線全長80.903公里。由中鐵四局承建03標段,標段位于安徽省鳳陽縣及五河縣境內,線路全長9公里,該橋塔身高度達到148.6m,精度要求高,是全線重點控制性工程。

                                                                              淮河特大橋主墩承臺整體尺寸為22.95m*29.2m*6m(順橋向*橫橋向*豎向),近乎于1個標準籃球場大小,此次累計澆筑混凝土方量約4027立方米。為確保大體積混凝土澆筑質量,項目團隊提前謀劃,制定了詳細的專項施工方案,對人員配備、機械配置、監控檢測、安全管控等方面做了周密安排。施工中,承臺采取豎向分層,橫向分段的澆筑形式,從四周向中心推進,嚴格控制分層厚度,按標準實施每道工序,確保整體澆筑質量。

                                                                            32.jpg
